Description

[Detailed Description of the Invention] Technical Field The present invention relates to a rear door locking device for passenger cars and commercial vehicles.

Conventional technology Conventionally, in the case of passenger cars and commercial vehicles that have rear doors, rear doors have been designed with hinges at the top rather than double doors or vertically open doors with upper and lower hinges, in part because it is convenient for loading and unloading luggage and is easier to operate. The flip-up type is often used, but in this case, when the rear door is opened, the entire rear of the vehicle is opened, making it convenient for loading and unloading luggage, but on the other hand, warm or cold air from the rear of the vehicle is released into the atmosphere. This may seem like nothing at first glance, but it is a major problem in the rear of the vehicle, where heating and cooling effects are low.This not only reduces the comfort of the rear seats, but also makes the rear door of a passenger car feel vaguely like a commercial vehicle. As a result, while rear doors were convenient, they also had drawbacks, such as detracting from the image of a passenger car.

Purpose of the invention Therefore, the present invention divides the flip-up rear door into two parts, upper and lower, and uses the lower rear door as a hinge at the split position to provide a rear door locking device that can be opened and closed independently. The purpose is to prevent a decline in heating and cooling effectiveness and damage to the image of passenger cars.

Structure of the invention Fig. 1 is an overall configuration diagram clearly showing the structure of the invention, in which a flip-up rear door 3 that can be opened and closed by using a roof 2 portion as a hinge is attached to the rear of a vehicle body 1, and the rear door 3 is divided vertically into two to form an upper rear door 3A and a lower rear door 3B, and the lower rear door 3B is formed to be able to be opened and closed around the dividing position, and is further engaged with each of the upper rear door 3A and the lower rear door 3B. The rear door locking device is provided with an upper hook 4 and a lower hook 5, and a release means for releasing the engagement with the upper rear door 3A or the lower rear door 3B, respectively.

Embodiment FIGS. 2 to 7 are drawings of an embodiment of the present invention, in which a jump-type rear door 8 that can be opened and closed by using the roof 7 portion of the vehicle body 6 as a hinge is vertically extending 2 minutes from the rear door 8. upper rear door 8A and lower rear door 8
B, and the lower rear door 8B
is attached via a hinge 9 in a vertically divided position so that it can be opened and closed independently.

In the rear floor 10 of the vehicle body 6, a lower hook 12 that engages with an engagement hole 11 formed in the lower rear door 8B is rotatable about a pin 13 and biased in the engagement direction via a spring 14. It is attached so that it can be disengaged by pulling the wire 15 by operating the rear door opening knob on the driver's seat in this state, and is engaged with the engagement hole 16 formed in the upper rear door 8A on both sides of the rear end of the vehicle main body 6. The upper hook 17 is rotatable around a pin 18 and is attached to the upper rear door 8A so that it can be engaged and disengaged by pulling a wire 19 by operating a newly installed hatchback/notchback switching knob on the driver's seat. A slide bar 20 is attached to the lower rear door 8B in conjunction with the upper hook 17, and moves downward when the upper hook 17 is engaged, and moves upward when the engagement is released, with its sliding direction being regulated by a guide piece 21. The spring 2 is inserted into the engagement hole 22 formed in the upper rear door 8A.
A connecting hook 24 that engages with the biasing force of 3 is rotatably attached around a pin 25, and a rubber gutter 26 for drain discharge is attached between the upper rear door 8A and the lower rear door 8B. In addition, an auxiliary connector 27 that also serves as a spring for lifting the lower rear door 8B is installed, a shock absorber 28 for lifting the upper rear door 8A is installed between the vehicle body 6 and the upper rear door 8A, and a shock absorber 28 for lifting the lower rear door 8A is installed.
A handle 29, which also serves as means for releasing the lower hook 12, is attached to the surface of B. In the rear door locking device configured as described above, when the hatchback/notchbuck switching knob is switched to the notchbuck side by, for example, pulling, the upper hook 17 becomes the state shown in FIG. 5 and fixes the upper rear door 8A to the vehicle body 6. At the same time, the slide bar 20, which has moved downward in conjunction with the hook 17, releases the connecting hook 24, so if the driver pulls the rear door opening knob to release the lower hook 12 in this state, only the lower rear door 8B opens. is opened as shown in FIG. 6, and the rear door 8B is opened and closed, and only the lower rear door 8B is operated to open or close.

Next, if you push back the hatchback/notchback switching knob and switch it to the hatchback side,
Since the upper hook 17 moves upward together with the slide bar 20, the engagement of the upper hook 17 is released and the connecting hook 24 is engaged, so that the upper rear door 8
A and the lower rear door 8B are integrated, and in this state, when the driver pulls the rear door opening knob to disengage the lower hook 12, the upper rear door 8
A and the lower rear door 8B are integrally opened as shown in FIG. 7, and the hatchback rear door is opened, and the rear door 8 is opened and closed in the hatchback state.

Note that the shape, operation, etc. of each of the hooks 12, 17, and 24 may be of any configuration other than those of this embodiment.

Effects of the invention The present invention divides the flip-up rear door into upper and lower halves, and provides a rear door locking device that allows the lower rear door to be opened and closed independently around the divided position. This has the effect of preventing a decline in the cooling effect and damage to the image of passenger cars.
